DEVICE HANDLING LOAVES OF CHEESE.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filedFebruary 11, 1916. Serial No. 77,802.

To all whom it may concern Be it known that I, DAVID Lonn'rsorrnn, railway servant, a citizen of the Swiss Confederation, residing at St. Leonhardstrasse No. 70, St. Gallen, Switzerland, have invented new and useful Devices for Handling Loaves of Cheese, of which the following is a specification.

The present invention relates to a new and useful device for handling loaves of cheese. It is well known that the loaves are stored in the cellars on shelves and that the loaves have to be turned, salted, cleaned, etc., at regular intervalsof time. One object of the present invention is to provide a device which makes the lifting and turning of the loaves more easy and to do away with manual operations as far as possible.

The present invention also comprises other features which will appear in the course of the subjoined description.

ieference is to be had to the accompanying drawings forming part of this specification in which similar characters of ref erence indicate corresponding parts in all the figures.

Fig. 8 is a front view thereof.

Fig. 9 is a sectional elevation on line E-F of Fig. 7;

Fig. 10 shows part of the driving gear for the device to turn the loaves;

Fig. 11 is a front view of the same device.

The device shown in Figs. 1% comprises a rectangular rigid frame 1 made of wooden beams. The frame 1 is arranged on rollers 2 and carries two standards 3 which are rigidly connected to the frame 1. The stand ards 3 are interconnected by a cross beam 4 rigidly fixed to the top of said standards 3, and are held by stays 6. The standards 3 serve as guides for a stage 7 which is movably arranged thereon. The stage 7 is suspended on a chain 8 running over guide rollers in the well known manner, said chain 8 passes over a chain drum arranged on the cross bar 4. By turning the chain drum the stage 7 is raised or lowered according to the direction of rotation. On the axle of the chain drum I arrange a worm wheel 12 with which a worm 11 is in engagement. On the shaft of the said worm a chain wheel. is fixed over which an endless chain 10 passes. The chain 10 passes nearly to the ground. On the stage 7 a table 13 is removably arranged. The table 13 is provided on its top 17 with rollers 14 rotatably mounted parallel to each other. The rollers 14 are covered wholly or partly with an india rubber coating or the like. Between the rollers 14 a wing 15 is hinged to the table top 17 by means of hinges l6 and to the wing 15 there is another smaller wing 19 connected by means of hinges 18. In the path of the wing 15 there is a detent 2O fixed to the table 13 in such a manner that raised out of the plane of the wing 15 as soon as the latter is swung downward. To hold the wings 15, 19 in the plane of the table top I provide stays 21 rotatably mountd on the table 13 and connected to hand levers 22 by means of which the stays 21 may be brought in or out of engagement with the Wings l5, 19. On the frame I arrange a platform 23 which is rigidly fixed thereto. In the platform 23 two rollers 26 are rotatably mounted and two wings 24L. 25 are hinged thereto. The wings 24E, 2 3 are held by springs in such a manner that they are flush with the platform when out of use. Beneath the wings 24C, 25 there is a board 30 and at the ends of the wings 2 1, 25 there are boards 28, 29. The boards 28, 29, 30 are rigidly fixed to the frame 1, they serve as rests and stops for the loaf to be turned.

To handle loaves of cheese which are situated on the shelves the stage 7 is moved until the rollers 14 are near the loaf desired. The loaf is lifted by hand on the rollers 14 and moved thereon so far that by tilting the loaf the edge of it comes to rest on the wing 15. If the stays 21 have been removed previously the wing 15 will swing downwardly and upon striking against the detent 20 the wing 19 is raised out of the plane of the wing 15. The parts assume thereby the position shown in Fig. 1. In this position the loaf may be cleaned, salted and. attended to in the the wing 19 is Fig. 4.

stage 7 (Fig. 8).

usual manner. To bring the loaf back on the shelf the loaf is laid down upon the rollers 14 and moved thereon.

The platform 23 is used for loaves resting near the ground. The table 13 is removed and the loaf of cheese is moved on to the roller 26 and then tilted whereby the loaf and the board 24, 25 assume the position shown in Fig. 5 by dotted lines.

The device may be used for raising and lowering loads of any kind as shown in In the device shown in Figs. 7 to 11 the stage 7 and the rollers 14 are moved by means of an electro-motor 31. The motor 31 is arranged on the frame 1 and drives by means of a worm 32 and a worm wheel the shaft 41. On shaft 41 there is fixed a chain wheel 42 which drives by an endless chain 10 a chain wheel fixed on the shaft of a worm 11 and thereby the worm wheel 12 and the chain drum 40. tion of rotation of drum 40 the stage 7 is raised or lowered in the manner described above. The direction of rotation of drum 40 is altered by changing the direction of rotation of the rotor of the motor 31 which may be effected in the well known manner by means of a switch 33. The switch 33 may be actuated by means of a bar 34 from the stage 7 the bar 34 extending vertically upward in such a position that the same may be easily grasped by the operator standing on the stage 7. To set the stage 7 in or out of motion there is a clutch 37 arranged on the shaft 41 which clutch may be brought in or out of engagement with the chain wheel 42 and with another chain wheel 43. To move the clutch 37 I provide a lever 36 pivoted at 33 and which is connected with a bar 35 running vertically along the standard 3 in such a manner that the same may be easily grasped by the operator standing on the stage 7. The chain wheel 43 drives by means of a chain 51 a chain wheel 52 rotatably mounted on the standard 3 and moreover a chain gear 54 fixed on a shaft rotatably mounted in the Shaft 55 drives two rollers 38, 39 by means of chains or the like, said rollers 38, 39 are rotatably mounted in the stage 7. The rollers 38, 39 drive by means of chains and chainwheels the rollers 14 arranged on the table 13. The rollers 14 are interconnected by means of chains. In the frame 1 two friction disks 45, 46 are mounted on a common shaft 47 rotatably arranged on said shaft 36. Each of the disks (iopies of this patent may be obtained for According to the direc to be brought 45, 46 may be connected with the shaft 47 by means of a clutch adapted to be actuated by hand. On the shaft 47 two pulleys are fixed one of which drives the roller 43 and the other a roller 49. On the roller 49 the one edge of a band 50 of cloth is fixed the other end of which is attached to a second roller 49 not shown in. Fig. 10. The loaf to be attended is fed over the rollers 39, 48 which are set in motion by the clutches 44, 43 until the edge of the loaf is well over the band 50. The latter is now unwound by suitable rotation of the shaft 49 and the loaf yields taking by and by a vertical position resting on the band 50. To remove the loaf again the band 50 is stretched again by giving the roller 49 rotation in the opposite direction until the leaf again rests on the rollers 39, 48. Said rollers move the loaf again in the desired direction. The rollers are suitably covered with adhesive material for instance with india rubber.

The device shown in Fig. 10 may be applied as well to the table 13 replacing there the wings 15, 19.

Various changes may be made without departing from the spirit of my invention but What I claim is:

1. A device for handling loaves of cheese comprising a frame mounted on rollers, a stage movable in vertical direction on said frame, rollers arranged on said stage adapted to be brought below the loaves and to move the same to and from the stage, means co-aoting with said rollers adapted to tilt the loaves.

2. A device for handling loaves of cheese comprising a frame mounted on rollers, a stage movable in vertical direction on said frame, rollers arranged on said stage adaptbelow the leaves and to move the same to and from the stage, a table,

. wings hinged to said table adapted to swing downward, stops arresting said wings adapted to hold the loaf in its vertical position.

3. A device for handling loaves of cheese comprising a frame mounted on rollers, a stage movable in vertical direction on said frame, rollers arranged on said stage adapted to be brought below the loaves and to move the same to and from the stage, means eo-acting with said rollers adapted to tilt the loaves, a flexible band between said rollers, means to loosen and to stretch said band substantially as shown and described.

In testimony'whereof I afiix my signature.
